A proposed German law could force suspected Islamic extremists to wear electronic tags without trial. Justice Minister Heiko Maas said Monday he wanted to extend the use of the ankle monitors to cover those deemed a possible terror threat even if they haven’t been convicted of a crime.

Maas said the proposal was a “preventive offensive” against Islamic terrorism.

“The use of ankle tags should not be only available for convicted criminals after release from prison, but for those identified as a general threat as well.”
